SLIDING WINDOW- Patented April 10, 1966.

Application filed June 16, 1904. Serial No. 212,846.

To all whom, it may concern:

Be it known that we, WILLIAM J. D. THOMPSON and WILLIAM BENTLEY, o" thecity of Toronto, in the county of York and Province of Ontario, Canada,have invented certain new and useful Improvements in Slidin Windows; andwe hereby declare that the f0 lowing is a full, clear, and exactdescription of the same.

In our concurrent application, Serial No. 195,312, filed February 25,1904, we have shown and described a window and windowframe in which thenecessity of allowing for the swelling and shrinking of the windowsashand its guideways may be dispensed with by fitting each side of thewindowframe with a single window-guide and providing the window-sashwith guiding members, each having two contact-points to engage theopposite sides of the window-guides and hold the window-sash relativelythereto when stationary and during its sliding movements, and to effecta substantially tight contact of the window-sash when closed with thewindow guides the latter have on their outer surfaces raised offsetsonto which ride the outer contact points of the guiding members as thewindow-sash slides mto its closed position to draw it tightly againstthe inner or adjacent faces of the window-guides and not only preventthe inlet of air-currents between the window-sash and guide- Ways, butalso render it impossible for the window-sash to vibrate under ordinaryconditions. When opening the window, the outer contact-points move fromthe raised offsets as the window-sash begins to slide into its openposition, and the inner contactpoints then eXert themselves upon theinner surfaces of the window-guides to press the window-sash away fromthem, so that by being clear of contact with the window-guides it mayslide freely in its fixed pathway.

To prevent the inlet of air-currents through the space between themeeting-rails of the upper and lower window-sashes is the object of thepresent invention, and to attain this object one of them is fitted witha weathershield positioned by an actuating mechanism when thewindow-sashes are in their closed position to engage the otherwindowsash and cover the space between their meeting-rails, theactuating mechanism being arranged to position the weather-shieldagainst the adjacent part of the window -sash to -window-sill b which itis affixed to allow of the window-sash being opened or closed.

In streetcars and other transportationvehicles each window consists of asingle window-sash arranged when closed to sit upon an inclinedwindow-sill extending to or beyond its inner surface for the purpose ofshedding the water to the outside of such vehicle. To provide for thesliding movement of a window-sash of this character, it has heretoforebeen necessary to arrange its guideways so that the front window-guidewill be substantially straight or parallel with the front of the car orvehicle and the other inclined or divergent from the front one, so thatwhile holding the top end of the window-sash between them they willpermit its lower end to move laterally from and then slide downwardlypast the window-sill when the window is being moved into an openposition, the lower edge of the window-sash when closed being maintainedin position upon the window-holding springs e11- gaging the a acentfaces of the divergent window-guide.

By constructing the window-frame and. window-sash according to ourprinciple as outlined. above and hingin to the outer surface along thelower edge of the window-sash a spring-tensioned weather-shield toengage the Window-sill when the Window-sash is in. its closed positionwe are able to slide the window-sash in a vertical pathway parallel withthe front of the car or vehicle, and by fitting it with suitablewindow-holding locks we are able to maintain it in any adjusted positionand avoid the necessity of seating it when closed upon the window-sill.

In the drawings, Figure l is a front elevation of a window-frame andsliding windowsash adapted for building purposes. Fig. 2 is a similarview of a window-frame and sliding window adapted for cars and boats.Fig. 3 is a vertical section on the lines a a, Fig. 1. Fig. 4 is asectional view of the lower part of the Window-sash shown in Fig. 2,illustrating the position of the weather-shield and actuating mechanismwhen the weathershield engages the window-sill. Fig. 4 is a similar Viewto Fig. 4, showing the window-sash raised to enable the weather-shieldto clear the top of the water-shed for the window-sill. Fig. 4 is asimilar View to Fig. l, showing. the window-sash moving downward pastthe window-sill. Figs. 5 and 6 are perspective views of theweather-shield and springtensioned hinges shown in Figs. 3 and 4,respectively. Fig. 7 is a perspective view of a portion of theweather-shield and one of the hinges shown in Fig. 6 looking at it fromthe opposite side to that shown in that view.

Like letters of reference refer to like parts throughout thespecification and drawings.

To close the opening between the meetingrails a and o of the upper andlower windowsashes, (shown in Fig. 3,) we employ aspringtensionedweather-shield w, (shown in Fig. 5,) which extendscompletely across the meeting-rail a of the lower window-sash and isconnected to the bottom surface of the meetmg-rail by spring-tensionedhinges consisting of hinge members 0 and d, hinge-pins z, andtension-springs 2. The hinge members a are attached to the meeting-railu and are contained in countersunk recesses y therein, and the hingemembers cl are riveted or otherwise attached to the weather-shield w,which swings with the hinge members (1 upon the hinge-pins 2 whenactuated by the pull-rod .2 or the tension-springs z to respectivelydisplace it from the countersunk seat '0 in the meeting-rail U whenopening either of the window-sashes or to replace it in such seat whenclosing them. Attached to the top of the meeting-rail u is a slottedplate a, through which projects the pull-rod 2", the slotted plateacting as a stop to limit the movement of the pull-rod 2 in thedirection indicated by arrow in Fig. 3, so that the weather-shield willnot drop below the plane of the under side of the meeting-rail u whenthe window-sashes are opened.

To open the window-sash, the pull-rod z is drawn toward the meeting-railu to lift the weather-shield to out of the countersunk seat in themeeting-rail i), so that the top of the meeting-rail will be disengagedfrom the abutting shoulder 12, which forms with the weather-shield whenin the countersunk seat Q) a lock to prevent the lower sash being raisedor the upper sash lowered. When the weather-shield is displaced from thecountersunk seat 4/, either or both of the sashes may be moved intotheir open position, and when the sashes are both closed thespring-tensioned hinges replace the weather-shield in its seat 1;.

In the construction shown in Fig. 4 the weathenshield is contained in agroove 6, formed in the bottom bar 9 of the windowsash and is connectedto it by spring-tensioned hinges consisting of hinge members 0 and d,hinge-pins 2, and tension-springs 2, similar to those shown in Fig. 5.Attached to the weather-shield w are arms 0 to be engaged by the hookedends 'i of the liftingrods f, which are slidably contained in a recessg, formed between the bottom bar q of the window-sash and acovering-plate Z, immovably connected to it so as to allow of the freeaction of the pull-rods. The pull-rodsf have at their upper endshand-grips 71 to be engaged by the fingers of the operator whenactuating the pull-rods to position the weather-shield within the groovee" a When the window-sash is closed, the spring-tensioned hinges pressthe weather-shield it) into the position shown in Fig. 4, so that itslower edge will engage the top of the window-sill j on the outer side ofthe water-shed it. To open a window of this character, it is necessarythat the window-frame t be so arranged that the window-sash will have alimited upward movement of a sufficient distance to allow the lower edgeof the Weather-shield to rise above the top of the water-shed k, and toeffect this movement of the window-sash its guideways a are extended acorresponding distance above the window-top. By lifting on the pull-rodswhen in the position shown in Fig. 4 the window-sash is raised into theposition shown in Fig. 4 so that the lower edge of the weather-shieldwill rise above the top of the water-shed 7c and then enter the chamber6, as shown in Fig. 4*, so that it will be within the plane of the outersurface of the window-sash to enable it to move freely past thewindow-sill during its downward movement. When it is necessary to closethe window-sash, it is raised to the same height as shown in Fig. 4 thatis, until the weather-shield rises to at least the level of the top ofthe water-shed, over which it moves and then descends into the positionshown in Fig. 4. In the covering-plates Z, at or near their upper ends,are slots m through which extend the hand-grips h of the pull-rods, theslots being of a sufficient depth to allow of the free movement of thepull-rods when actuating the weather-shields.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. The herein-described article of manuf acture comprising a slidingwindow having a longitudinallydisposed groove in one of the horizontalsash-rails, extending from one side to the other thereof, aweather-shield contained in and extending from end to end of saidgroove, spring-tensioned hinges connecting said weather-shield to thewindow-sash within said groove and a pull-rod to position theweather-shield within the groove during the sliding movement of thewindow-sash.
